Plus has different behavior on Google mail, is why.
Foo+anything@ goes to foo@. This is an easy way to track who's selling your email.
Not every complaint you don't understand is invalid
The world won't change because you say so. Just use a dash to separate your constituent parts instead of a plus sign, and you won't have that problem ever again.
(I know someone who has been complaining about exactly this for more than twenty years now. Surprisingly it never seems to get old for him. Some people just need a "standard complaint".)
